“…Moreover, harmonic and interharmonic components have been taken into account in analyzing the frequency domain. In [17], the performance of different chaotic models including Chua, Lorenz, and Rössler is assessed based on the power quality indexes of the DC electric arc furnace loads. Power quality indexes including THD, TIHD, normalized instantaneous distortion energy (NIDE) ratio, and the short-term flicker severity (P st ) are considered in this work.…”

Conventionally, DC arc furnaces are fed by thyristor rectifiers to control the level of current or power transferred to the load. With the advancement of high-power transistors, other structures such as diode rectifiers and DC choppers have been introduced and developed for the feeding system of DC electric arc furnaces. In this paper, the effect of different power supply systems on power quality indexes is discussed. In this regard, two types of feeding systems are considered, including a power supply system based on thyristor rectifiers and a power supply system based on diode rectifiers and DC choppers. In addition, different control methods, including constant current control (CCC) and constant power control (CPC), on DC electric arc furnaces are applied. For evaluating the power quality indexes, voltage and current harmonic distortion, unbalance of voltage and current, and power factor on the AC side are investigated for different power supply systems. Simulation results were performed with PSCAD/EMTDC software. It is shown that the power supply systems with diode rectifiers and DC choppers have superiority in comparison to the types based on thyristor rectifiers. According to the results, the average current THD is reduced from 16.55% in the thyristor rectifier to 8.40% in the chopper rectifiers with the CCC method and from 19.27% in the thyristor rectifier to 7.38% in the chopper rectifiers with the CPC method. Moreover, the average voltage THD is reduced from 5.67% in the thyristor rectifier to 3.02% in the chopper rectifiers with the CCC method. The result is similar to the CPC method. Furthermore, for a specific power supply system, the harmonic distortion is lower in the case of the CPC method than in the CCC method.

Most renewable energy sources are operated in direct current (DC) and require dedicated inverter to be integrated in the power system. This results in loss of rotational inertia as well as degradation of the power quality (PQ) indices. A promising alternative is represented by low-voltage DC grids, whose standardization though is still incomplete. Reference systems are being developed for DC metering and DCPQ, but their validation requires inter-laboratory comparison. To this end, we propose the design and preliminary characterization of a transfer standard for DCPQ measurements. The obtained results confirm the reliability of the proposed architecture, that guarantees a worst-case power uncertainty of 1 % over the frequency range from DC to few tens of kHz.
